IMPROVEMENT IN ATTACHMENTS 0F BAND-CUTTEHS AND THRASHING-MACHINES.

Specification forming part of Letters Patent No.118,634, dated August 29, 1871.

To all 'whom 'it may concern:

Be it known that we, SAMUEL C. MYERS and JAMES MCGAULEY, of McAllisterville, in the county of Juniata and State of Peimsylvania, have invented certain Improvements in the Attachment of Band- Cutters and Separators, of which the following is a specification, reference being had to the accompanying drawing.

Our invention relates to thrashing-machines; and the invention consists in a novel method of connecting a band-cutter to the machine and operating the same therefrom, as hereinafter more fully explained.

The accompanying drawing is a perspective view of a portion of a thrashing-machine with our improvement applied thereto.

Our present invention has for its object the providing of means for operating a baild-cutter in connection with a thrashing-machine, and so arranging them that the band-cutter can be operated from the thrashing-cylinder, and connecting it therewith in such a manner that the bandcutter, which also conveys the bundles 'from the mow or stack to the thrasher, can be turned in any desired direction, and also be located on either side of the machine.

In the drawing, l) represents a band-cutter and conveyer patented to us on the 31st day of January, 1ST 1, and to which patent reference is made for a more full description thereof. A represents the frame, and C the cylinder of an ordinary thrashing-machine. At each side of the feeding-table, near the throat or front end ofthe thrasher, we secure a horizontal platform, B, semicircular in form, and under the center of each of these we mount a vertical roller or pulley, c, the aXis of which extends up through the platform B, as shown in the drawing. This pulley c is connected by a belt, j', with a pulley, o, on the shaft or journal of the thrashing-cylinder C outside of the frame. The lower or front end of the band-cutter D is connected by a yoke, e, and rod l, or equivalent device, with the projecting axis of the pulley c, which termina-tes in a hook, a, for that purpose, the bolt l having a screw-thread cut on it, by which it is connected to the yoke e, and by means of which the parts can be adjusted so as to keep the band-cutter close up to the edge of the platform B. Underneath the platform B a belt, g, extends from the pulley c to the front roller or driving-shaft b of the band-cutter, by which motion is imparted to the latter and to the conveyer-belts thereof, as shown in the drawing.

With the parts thus arranged, it will be seen that the band-cutter, when attached, will have mot-ion communicated to it from the cylinder C through the medium of pulley c and belts j' and g, and, as the band-cutter is attached to the platform B at a point concentric with the pulley c, it follows that it can be swung around laterally, as indicated in dotted lines, to the extent of almost the half of a circle, and that thus it can be extended to receive and bring the bundles from any point where they may happen to be, on that side or in rear or front of the machine, and, as the same provision is made for connecting and operating it at the opposite side of the machine, it follows that the bundles can be delivered from any desired direction to the person feeding the machine, the bands of the bundles being cut as they are thus delivered, as described in our patent hereinbefore referred to.

In attaching the band-cutter to the opposite side of the machine it can either be driven from a corresponding pulley, o', on the opposite end of the cylinder C, or a belt may be run from one of the vertical pulleys c across to the opposite one, and thus the band-cutter be always driven from the same pulley o, whichever side of the machine it may be located. This may sometimes -be necessary in order not to interfere with the belt or other means by which mot-ion is imparted to the thrashingwcylinder; though, in making new machines, we prefer to make them so that the cylinder G may be driven from either end.

In practice the bolt or rod lwill not be attached to the shaft or axis of the pulley c, but it should be attached at a point concentric therewith, so that, however the band-euttcr may be moved laterally, the belt g will always remain tight and uniform in its pressure, and thus drive the band-cutter in any of its various positions.

It is obvious that, instead of using belts and pulleys, gearing may be substituted and the operation be the same, the main idea being to operate the band-cutter from the thrashing-cylinveyer D with the semicircular platform B, havder, and to so arrange it that it can be swung ing` the driving-pulley o located at the center around in any direction, as described. thereof', as set forth.

Having thus described our invention, what We claim isl. In combination With the platform B, the adjustable or movable band-cutter and conveyer D, Witnesses:

arranged to operate substantially as set forth. J. WV. MATHERSBURGH,
